Recently got LINQPad which is an awesome tool for LINQ new bees. It comes preloaded with 200 examples of how to use various forms on LINQ, LINQ to SQL and LINQ to XML.
LINQPad is more than just a LINQ query tool. It actually is a code snippet IDE. Instantly execute any C# 3 or VB 9 expression or statement block!
Best of all, LINQPad is free and needs no installation. Just download and run. The executable is only 2MB and is self-updating.
